[0002] In the process of producing marshmallows, it is important to control the environmental humidity in the production area. If the humidity is too low, the marshmallows will be too fluffy and dry, resulting in poor viscosity and difficult to shape; if the humidity is too high, the marshmallows will melt easily. In response to the problem of environmental humidity during marshmallow production, Chinese utility model patent CN218303253U discloses a burner device that is easy to humidify. Through the humidification component, a humidifying object is added to the sugar-making chamber from bottom to top along the hollow rotating shaft, and the high temperature of the burner is used to heat the humidifying object into steam, and then the steam is used for humidification. This method has the following problems: 1. The humidifying object will absorb a large amount of heat from the burner in the process of being heated into steam, which will affect the temperature of the burner and thus affect the production of marshmallows; 2. Steam is generated slowly, the amount of steam is small, and the humidification efficiency and humidification effect are poor; 3.
